The contents of C must support concatenation into an N-dimensional rectangle. Otherwise, the results are undefined.And it was awful. Given past reputation of inefficiency, I still don't trust looping in Matlab. Post-R2016b, one can convert a string array to cell array with num2cell and then to table with cell2table. Table can be written to csv file with writetable. This is actually fast, as writetable is fast. Only num2cell slows down the whole process a ...Just like other container classes (e.g. cell array, string array), if you want to access the content of a table you need to use curly braces (not parentheses): Theme.

But all the cells in this field are not strings. How to convert their class? If I check their class class(EEG.event(1,4)) I obtain struct. First, I thought to check which cells are not strings:cell2mat is doing precisely the correct thing as documented here. Each cell element is char vector of size 1xN. Your overall cell array is 1xN.cell2mat concatenates the contents of every cell in the "natural" direction as defined by the shape of the cell array. Your original cell looks a bit like this:. FooCellArray = [{'Foo1'}, {'Foo2'}] The effect of cell2mat is basically as if you removed ...1. Well, does indeed use the colon operator, and will give the same result as cell2mat (phone_record). Another non-colon solution is. cellfun(@(x) x, phone_record).'. with the benefit of transforming the structs on the fly, for example adding (missing) fields. Here we use the idendity, of course.The commands class(btl_data.POLYGON) returns 'cell', and iscellstr(btl_data.POLYGON) returns 0. The commands char(C.B) and cellstr(C.B) fail (Element 1 is not a string scalar or character array.

Azzi showed you how toCopy. join (erase (string (Exampletable {:, :}), & If str is a string array or cell array of character vectors with multiple elements, then pad adds space characters. All of the strings in newStr are as long as the longest element in str.. If str is a character vector, or a string array or cell array of character vectors with one element, then pad returns str unaltered. Your job is to convert the string array to a cell a Because cell2mat simply concatenates the contents of the cells, which are strings, so you get a single string instead of several numbers.
